Since I don’t really know where to post this I’m doing it here…
They should trap; *DOCUMENT* MouseMove and MouseUp events for their Window control instead of the handle at the top…
Only the MouseDOWN event should be trapped when creating Windows on the actualy window object itself … ;)

a more explicit explanation would be appreciated, preferably with some example source code which illustrates what should be done.

then, also, you should also raise exactly the same issue with GWT because the code was lifted directly from GWT 1.2, but i’ve been comparing it against GWT 1.5 and there’s no significant differences that i can find.
